Edward Sharpey-Schafer (1850-1935), British physiologist. Sharpey-Schafer is best known for his work on hormones. He termed the coin 'endocrine' for the secretions (hormones) of the ductless glands. Along with the English physician George Oliver (1841-1915), Sharpey-Schafer discovered the hormone adrenaline in 1894. He also predicted the existence of insulin, at the same time coining the name for it.
